On the move, forces
- Force Is measured in N Nutons
- Pressure is measured in Pa Pascals
- The Fist aeroplane flighs where by the
Wright brothers.
- It lasted 12 seconds, and only reached 3
meters high.
- The First car was built in 1796 in France by
Nicholas Cugnot. It went about 2 miles an hour.
- It lasted 12 seconds, and only reached 3
meters high.
- A modern snowmobile, its catrpillar
track are wide so, they do not sink into
the ground and so they can go fast.
- There are other uses of transport that are not as obvious.
EG, Electricity is generated in power stations
- These all need transport to build
- Without power stations, noting would really work
- Without power stations, noting would really work
- These all need transport to build
- Water and Air Resistance are types of
drag.
- Knower days, they design car and other vehicles
more streamlines so then they can go faster and
while using less petrol.
- More streamlined it is , less drag on the object
- Cars have deflectors on the top to get the air
particles just to bounce off them.
- Athletes often to the same for being as
streamlined as possible
- Cars have deflectors on the top to get the air
particles just to bounce off them.
- More streamlined it is , less drag on the object
- Knower days, they design car and other vehicles
more streamlines so then they can go faster and
while using less petrol.
- Lorries travelling at a steady
speed, has a balanced force
- To balance it out, the engine pushes it along
- If there is less drag, the lorry will not need
such a big force form the engine.
- If there is less drag, the lorry will not need
such a big force form the engine.
- To balance it out, the engine pushes it along
- Wind can take affect on a moving object
- This is called drag
- The faster / stronger the wind, the slower
you are made to go
- The faster / stronger the wind, the slower
you are made to go
- This is called drag
- Pressure effects everything
- A piece of metal that can attract other metals is a magnet
- This is called magnetism
- Magnets only can attract certain types
on metals
- These are Iron, NIckel and Cobalt
- Steel is a mixture of mostly iron, so it is a magnetic
material too
- Steel is a mixture of mostly iron, so it is a magnetic
material too
- These are Iron, NIckel and Cobalt
- Magnets only can attract certain types
on metals
- This is called magnetism
- An Electromagnet is a magnet made using electricity
- It is a magnet with electricity curret flowing through it
- The North and South poles of n
electromagnet depend on which way
the current is flowing through the wires
- You can increase the strength of an electromagnet by
- Increasing the number of coils of wire
- Increasing the current in the wire
- Using a magnetic material for the core
- Increasing the number of coils of wire
- You can increase the strength of an electromagnet by
- The North and South poles of n
electromagnet depend on which way
the current is flowing through the wires
- It is a magnet with electricity curret flowing through it
- All different forms of transport need to be
controlled, so they stay safe
- Aeroplanes are controlled using
special flaps on the wings and on
the tail.
- The Attitude describes how much the plane is
tilted compared to the horizon
- The Attitude describes how much the plane is
tilted compared to the horizon
- Ailerons are the pit at the end of the wings
- The Ailerons are used to
tilt the aeroplane from
side to side
- The Ailerons are used to
tilt the aeroplane from
side to side
- Aeroplanes are controlled using
special flaps on the wings and on
the tail.
- Forces can move objects by turning them around a pivot
or fulcrum.
- A long lever and par which you push down
on one side you are applying an effort and
the object on the other end, the object then
moves up
- A long lever and par which you push down
on one side you are applying an effort and
the object on the other end, the object then
moves up
- A lever is used as a force
multiplier
- A small effort force has to move through a
greater distance than a multipliers force
- A small effort force has to move through a
greater distance than a multipliers force
- We use transport for many things, but not all of these are necessary
- Almost all transport
need a fossil fuel to
power it
- Burning fossil fuels is
not sustainable, because
we are using up non -
renewable energy
resources and
contributing to global
warming
